Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a multicast/broadcast single frequency network (MBSFN) subframe configured based on a unicast subframe structure, and transmits MBSFN signals for eMBMS using the MBSFN subframe. In a one configuration, the MBSFN subframe structure for eMBMS transmissions uses the same CP length, the same common reference signal (CRS) pattern and same subframe structure used for unicast, along with the same antenna ports used for unicast transmission. In another configuration, the MBSFN subframe structure for eMBMS transmissions uses the same CP length and same subframe structure used for unicast, but potentially different CRS patterns and different antenna ports from those used for unicast transmissions. In another configuration, the MBSFN subframe structure for eMBMS transmission uses the same CP length and same subframe structure used for unicast, but with a UE-RS pattern.
